Torsional Oscillation CharacteristiCS of Rotary Shafts Based on Torsion and Bending Coupled Vibration*
Transactions of Tianjin University: 2007, 13(4), 72-78，-0001，（）：
The torsionaI oscillation characteristics on the bending and torsioh coupled vibration of ro. tary shaft system were investigated using the elasto•-dynamic theery and other mathematic meth-ods, such as difference approach, Fourier transfOrm. and wavelet transform. It iS concluded that mass eccentricity and other exciting modalities affect the bending and torsion coupled vibration of ro. tary shafts. TorsionaI vibration caused by bending vibration features linearity along with the change of amplitude of bending vibration. Meanwhile, energy spectrum concentrates on high frequency are-a with the wavelet analysis.
